Summit Pond Water Garden Mosquito Control Dunk 6 pack

Biological Mosquito Control Dunks kill mosquitoes before they are old enough to bite. Mosquito Dunks float on water and will keep on working for 30 days or longer under typical environmental conditions. While floating they slowly release a long-term biological mosquito larvicide at the waters surface. This larvicide gradually settles in the water where it is eaten by mosquito larvae growing there. Mosquito Dunks may be used in all types of standing water sites where mosquito larvae grow. Alternate wetting and drying will not reduce their effectiveness.
